Hi Greg,
No problems mate, yes the transfer wasn't the best. although I think you have a point, my flats need to be more exposed! This problem occurred two weeks ago and I thought my flats back then were over exposed, so I backed off a bit. I use the "P" option on the dslr and adjust the A/E until I get the histogram one third from the left using Live view. I will amp it up a bit and see the results.
As I said before, I had gathered DSS may of been the problem, by simply reinstalling this problem usually remedies the issue.
So a big thank you to everyone who contributed, I appreciated your help
Regards Paul.
